My laboratory research explores alternative pre-mRNA splicing in prostate cancer (PCa) biology, and liquid biopsy-derived molecular biomarkers of treatment outcomes. My clinical research investigates chemo-preventative strategies to reduce low risk PCa progression, and surgical alternatives to cytotoxic chemotherapy for metastatic testicular cancer.

My laboratory-based research programme explores a link between alternative pre-mRNA splicing (AS), a ubiquitous post-transcriptional gene regulatory mechanism, and prostate cancer (PCa) phenotypes. During AS, coding (exons) and non-coding (introns) regions of a gene are shuffled to create protein isoforms with different functions. AS is regulated by trans-acting RNA-binding proteins (RBPs), and tightly coupled to transcription. We are studying the link between dysregulation of transcriptional and intracellular signalling processes and AS, mediated by RBPs.
Our translational research examines how blood-derived liquid biopsy molecular biomarkers can be used to improve treatment outcomes for PCa patients. With NHS colleagues, we are investigating minimally-invasive surgical alternatives to chemotherapy for metastatic testicular cancer to reduce the therapy burden and toxicity. In collaboration with the Wolfson Institute of Preventative Medicine, we are exploring how minimally-toxic chemo-preventative strategies may reduce PCa progression on active surveillance.
